可选的，本发明同样适用于一些只具备扬声器而无通信功能的电子设备中，这些电子设备无论是单声道还是双声道的形式，均不具有听筒的功能，通过本发明可将扬声器作为听筒与扬声器来用，因此，本发明的应用场合并非限制于移动终端。在一个实施例中，扬声器模组还包括低功率信号处理电路，连接在第一扬声器11接收信号端口的前端电路中，在本实施例中，第一扬声器11即连接在原有扬声器连接位置处，在第一后腔18上开设开窗部180后，在原有扬声器基础上实现了听筒的功能，进而具备了通信的能力。若第一扬声器11连接在原有听筒连接位置处，则无需设置低功率信号处理电路，采用原有电路即可完成扬声器代替听筒的功能。Optionally, the present invention is also applicable to some electronic devices having only a speaker and no communication function.These electronic devices do not have the function of an earpiece in either mono or dual channel form. The speaker can be used as an earpiece and a speaker by the present invention. Therefore, the application of the present invention is not limited to the mobile terminal. In one embodiment, the speaker module further includes a low-power signal processing circuit connected to the front-end circuit of the
每个扬声器后腔部件(包括第一扬声器后腔部件和第二扬声器后腔部件)均设置一个扬声器单独工作或者两个以上扬声器同时工作，具体的扬声器数量不作为限制，也就是说，第一扬声器11(第二扬声器12)可以表示一个扬声器，也可以表示两个以上扬声器。Each speaker rear cavity component (including the first speaker rear cavity component and the second speaker rear cavity component) is provided with one speaker working alone or two or more speakers working simultaneously, and the specific number of speakers is not limited, that is, the first The speaker 11 (second speaker 12) may represent one speaker or two or more speakers.
每个扬声器后腔部件的后腔(第一后腔或第二后腔)可以为单独一个腔体。或者，每个扬声器后腔部件的后腔可以为两个以上腔体组合而成，且用来组合形成后腔的腔体中的几个或全部能够被连通，以改变后腔的体积或结构。The rear cavity (first back cavity or second back cavity) of each speaker back cavity component may be a single cavity. Alternatively, the rear cavity of each speaker rear cavity component may be a combination of two or more cavities, and several or all of the cavities used to combine the formation of the rear cavity can be connected to change the volume or structure of the rear cavity. .

继续参看图5，在一个具体的实施例中，固定部件16为胶体，第一扬声器11通过胶体粘接在第一后腔18内，第一扬声器11的振动膜片封住第一后腔18的该部位。第一后腔18和终端1的出音孔15处的壳体之间还设有一圈介质物件13，该介质物件13可以是泡棉，胶水或其他形式的介质物件。除了用第一扬声器封闭的部位，第一后腔18还包括用来固定第一扬声器且上端具有开口的本体181，以及连接本体181以封闭开口的后盖182，可以方便组装和拆卸。参看图5、7和8，第一前腔是由第一扬声器11、第一后腔18开孔部分(该部分被第一后腔封住，并使得第一后腔能够辐射声音)、固定部件16的开孔部分，介质物件13的开孔部分构成，也就是这些部件上面形成有一个连通的开放腔体，该腔体就是第一前腔，可以为第一扬声器11辐射出来的声音进行导向，使声音朝一定方向传播。Continuing to refer to FIG. 5, in a specific embodiment, the fixing
参看图7和图8，设置在第一后腔18的开窗部180，不只限制在侧壁上，任何能达到后腔开放的位置均可。示例性的，开窗部180呈现为开孔状，开关部件17为一个与该开孔的孔径大小匹配的塞状部件。Referring to Figures 7 and 8, the
在图7中，需要听筒角色进行通信的时候，信号通过听筒的电路解码放大后输入给代替听筒的第一扬声器11，同时或者提前获取需要通信的需求触发开关部件17，开关部件17打开开窗部180，使得第一后腔18处于开放状态，第一扬声器11等效于没有添加后腔，相当于扬声器单体在进行工作，刚好覆盖听筒需要的通信频段。In FIG. 7, when the handset character is required to communicate, the signal is decoded and amplified by the circuit of the earpiece, and then input to the
在图8中，当用户需要开放扬声器听取音乐，免提或者其他外放需求的时候，开关部件17关闭开窗部180，使得第一扬声器后腔18处于封闭状态，可以设计成开关部件的默认状态是处于封闭的，只有实现听筒功能时进行开启。如图8所示，封闭第一扬声器后腔18的开窗部180后，此单元将作为扬声器使用，信号馈给此第一扬声器11走另外一条扬声器高功率处理电路(不走语音处理的电路)，配合另一声道的第二扬声器12同时工作，以达到双通道立体声效果的播放，如果在软件中植入虚拟环绕声算法，那么这个双通道的立体声扬声器也可以制造出环绕声的效果，使得整个播放效果更为饱满，更呈现空间立体感。In FIG. 8, when the user needs to open the speaker to listen to music, hands-free or other external demand, the
值得说明的是，本发明关于扬声器与终端内部的具体电性连接可以根据实际端子的情况进行连接配置，以使扬声器能够播放声音，因而在本发明对于电性连接部分不再进行赘述，本发明目的在于在扬声器后腔上开设开窗部并控制开窗部的开合以使扬声器能够在扬声器和听筒功能间切换。本发明关于第一后腔和第一前腔的内容，同样适用于第二后腔和第二前腔(若第二扬声器无需实现听筒声音，则可除去开窗部和开关部件部分的描述内容)。It should be noted that, in the present invention, the specific electrical connection between the speaker and the terminal can be connected according to the actual terminal condition, so that the speaker can play the sound, and thus the present invention will not be described in detail for the electrical connection portion. The purpose is to open a window opening on the rear cavity of the speaker and control the opening and closing of the window opening to enable the speaker to switch between the speaker and earpiece functions. The invention relates to the contents of the first rear cavity and the first front cavity, and is equally applicable to the second rear cavity and the second front cavity (if the second speaker does not need to realize the sound of the earpiece, theDescriptive content of the window opening and switch parts).
本发明虽然以较佳实施例公开如上，但其并不是用来限定权利要求，任何本领域技术人员在不脱离本发明的精神和范围内，都可以做出可能的变动和修改，因此本发明的保护范围应当以本发明权利要求所界定的范围为准。The present invention is disclosed in the above preferred embodiments, but it is not intended to limit the scope of the invention, and the present invention may be made without departing from the spirit and scope of the invention.
